Is it time for our break yet?

Not a whole lot went on this week at school. We're down to only about a week and a half left of classes before finals start kicking in. Compared to other finals weeks I've had at U of A, this quarter's finals week really doesn't look too bad :)

After our test on bacteria/viruses/antibiotics on Tuesday (which went pretty well), I was pretty dead tired and went to bed early that day. I woke up the next morning (Wednesday) and felt like I caught some type of stomach bug, so I spent the majority of the day resting in bed and sipping clear fluids (I had no appetite all day).

Then Wednesday late afternoon I had to go take a 3 hour CPR training and certification class (that I had signed up for a few months ago) for school. I managed to make it and felt okay through almost all of it. They did make us do 6 full minutes of chest compressions to the beat of "Another one bites the dust"... haha. So if anything, keeping that up was a little tiresome.

I'm feeling much better now, but still very tired. And unfortunately I'll have to do a bit more studying this weekend to make up for all the class I had to miss. I guess these things happen though.

We studied vital signs in my methods lab and practiced taking everyone's blood pressure. My blood pressure had been a tad high a few months ago, but I'm pretty sure all the running I've been doing lately has brought it down to a relatively normal level, so that's good to know I'm doing something right. The weight loss is still going pretty well also. I backtracked a little when family was in town a few weeks ago (we went out to eat quite a few times), but I managed to get back where I was and am down a total of 7 pounds, which I'm still pretty happy with considering everything I'm trying to keep up with :)

And speaking of running, my 5K is coming up and is next Saturday. I didn't get a lot of running done this week with being sick and all, but I'm still looking forward to next weekend. Should be pretty fun since quite a few of my class mates are doing it as well.

And really...that's about it. Until next time, hope everyone has a good week! :)

Optometry Fact of the Week

Esophoria

In optometry, when we talk about "fusion", we're referring to how you just see one image even thought you're using two eyes. I'm sure most people have seen someone with a strabismus, or a "lazy eye", where one eye tends to turn in or out from the other, but there's also something called a "phoria" that most people have without realizing it (like me).

A phoria has to do with how our eye muscles work "naturally" and where our eyes naturally want to turn when they're not actively looking at something. Fusion is still possible (meaning anyone with a phoria won't see double), but when we just use one eye, the other eye will go to it's "happy place" and rest in its natural position. We detect this with an alternating "cover test" where we cover one eye and quickly uncover it and cover the other. In someone that has a phoria, the eye that was just uncovered will generally move either in or out a little bit to refocus on what they're looking at.

This is a really good example of an "esophoria" (eso meaning inward). See how her eyes turn out a little whenever they're uncovered? Meaning her eyes naturally turn in when they are covered. (And actually, this girl has a tropia as well, meaning her left eye is like a "lazy eye")

Anyways! Esophoria is also what my eyes exhibit when only one of my eyes is covered. I'm only one of a few in my class. The rest are mostly exophoric (meaning their eyes naturally turn out) or they are orthophoric (meaning their eyes are aligned straight all the time). This isn't really a big deal or anything to be concerned about, but I find it interesting.

And I'm aware this is way more complex than what I usually talk about, but I find this stuff super interesting. And if I explain it out on here, it helps me study for my upcoming tests :)
